Step-by-step explanation:

The number of students who attended the orientation in that considered university was 432

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, first, let we assume the number of male students and female students who attended the orientation:

From the description, we have:

m = 5 times n = 5n

and

(m - 324)'s twice = n

or 2(m-324) = n

Thus, we get system of two equations as:

[tex]m = 5n\\2(m-324) = n[/tex]

Substituting value of m from first equation in second, we get:

[tex]2(5n - 324) = n\\10n -648 = n\\\\n = \dfrac{648}{9} =72[/tex]

Putting this value of n back in first equation, we get:

[tex]m = 5n = 5 \times 72 = 360[/tex]

Assuming that there were only two gendered students in university orientation (males and females), we get:

Total number of students who attended the orientation = m + n = 360 + 72 = 532

Thus, the number of students who attended the orientation in that considered university was 432

The total amount Holla paid for the shirt is: B. $18.74

Given the following data:

To find the total amount she paid for the shirt:

First of all, we would determine the discount on the shirt:

[tex]Discount = \frac{20}{100} \times 22\\\\Discount = 0.2 \times 22[/tex]

Discount cost = $4.4

[tex]Selling\; price = Cost\;price - Discount \\\\Selling\; price = 22 - 4.4[/tex]

Selling price = $17.6

Next, we would determine how much tax is to be paid:

[tex]Tax \;cost = \frac{6.5}{100} \times 17.6\\\\Tax \;cost = 0.065 \times 17.6[/tex]

Tax cost = $1.444

[tex]Total\;amount = selling \;price + tax\;cost\\\\Total\;amount = 17.6 + 1.444[/tex]

Step-by-step explanation:

Point (3,27) and (5,45)

m = (45-27)/(5-3)

18/2 = 9

Answer:

9

Step-by-step explanation:

To find the slope of a line, one of the methods is to look for the rise over run, or the change in y over the change in x. If we just look at the first few numbers on the chart, we can see that the change in y (for the first two numbers) is 18, and the change in x (for the first two numbers) is 2. So our slope is 18/2, or 9.

Answer:

The second one (Top right)

Answer:

f(x) = x - 2

Step-by-step explanation:

If you notice, the f(x) or y value is 2 less than the x value for every x value listed. This means that x - 2 = y. Just by rearranging this equation, you are given an equation in the linear form y = mx + b:

y = x - 2

Since the y coordinate is being represented by f(x) in the equation, as it is a function, the answer would be:

f(x) = x - 2
